Once upon a time there was a zoologist that collected butterflies.
And everyday he would set out in search of something new for his collection.
Until one day he was caught in an enormous lightning storm.
And because of this he need to find shelter immediately, luckily he found a cave entrance.
And because of this he discovered a new underground world to explore and collect, but he wasn’t properly equipped to do so, so he sat and waited and waited.
Until finally the storm passed and he was able to return home to grab all the gear he needed to mount an expedition.
And ever since that day he’s been on a journey to the center of the planet or so that’s what his family is telling everyone.
